We find it especially difficult to detect from other people's facial expressions whether they are

A) afraid.
B) angry.
C) lying.
D) disgusted.

While it can be challenging to accurately interpret all of these emotions from facial expressions alone, research has shown that people are generally better at detecting fear, anger, and disgust than they are at detecting when someone is lying. This is because lying often involves conscious efforts to conceal emotions or present false expressions, which can be more difficult to detect.
